With journalists, aid workers and U.N. officials largely cut off and local internet and mobile services blocked, much remains unknown about what has been happening in Ethiopia’s Tigray region over the last three months, but accounts emerging from farmers and villagers escaping the fighting between Tigrayan militia and central government forces are not encouraging.

U.N. officials have received multiple reports of sexual assaults and the executions of unarmed men and boys, and they report the discovery of at least 300 unaccompanied or separated children among the more than 57,000 people who have fled into neighboring Sudan. They believe hundreds more will be found among the hundreds of thousands of people displaced by fighting in the Tigray, Amhara and Afar regions.
